Patented July 31, 1934 PATENT OFFICE DISCHARGING MECHANISM N FORMING MACHINES John H. Moore, Detroit, Mich., assignor, by mesne assignments, to Andrew Ruen Hanger Co. Inc., a corporation of Michigan Application February 29, 1932, Serial No. 595,691

7 Claims.

My invention relates to a new and useful improvement in a release and discharging mechanism for forming machines, and adapted particularly for use on garment hanger forming ma- 6 chines. 'Ihe present invention forms in part, a continuation of, and in part, an improvement on my co-pending application, Serial No. 432,322 now matured into Patent No. 1,888,803 issued November 22, 1932.

It is an object of the present invention to provide in a forming machine of this class a mechanism, which will release the formed article and discharge it from the forming machine without interrupting the operation of the forming machine.

It is another object of the present invention to provide ina forming machine of this class a structure whereby the formed article may be discharged from the machine and automatically 20 placed upon a supporting rack.

Another object of the invention is the provision in a forming machine of this class of discharge mechanism -so constructed and arranged as to be durable and efficient in use, automatic in operation, compact, economical to manufacture, and simple in structure.

Other objects will appear hereinafter.

'Ihe invention consists in the combination and arrangement of parts hereinafter described and claimed. i

The invention will be best understood by a reference to the accompanying drawings which form a part of this specification, and in which,

Fig. 1 is a front elevational view of a'garment hanger forming machine embodying the invention. I

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1.

As shown in ,then'rawingsi the invetiopfi's' mounted upon a supporting bed 11 upwardly from which project the standards 12 and 1 3 supporting the hopperit.` A gear 15 'which is adapted to be` drivenby suitable source of 4power isxedl'y mounteaon' the shaft-16; which is cnnectedq through the clutchl'' to the shaft 13, onwhich.

.presser bar .41 by the spring 38. Fig. 5 is a fragmentary sectional view taken the gear 19 is xedly mounted. The clutch is operated by the yoke 20. The gear 19 meshes with the gear 21 which in turn meshes with a gear 22 xedly mounted on the shaft 23. A gear 23 is xedly mounted on the shaftA 23 and connected UU by the chain belt 24 to the gear 25 which is xedly mounted on the shaft 26, which shaft is journaled in bearings 27 and 28 mounted on the standards 12 and 13 respectively. A rotatable carrier 29 is used in conjunction with the inven- 05 tion, this carrier 29 being mounted lrotatably on the standards 12 and 13 and driven by the gear 21. 'Ihe carrier carries a plurality of forming and twisting mechanisms, which cooperate with', while not form- 70 ing a part of the structure which constitutes the present invention. On the carrier 29 which rotates in the direction indicated by the arrows in Fig. 5 and Fig. 3 is mounted a block 35 in which is formed a wire receiving slot 30 into 75 which the wire passes or is fed from the hopper 14 by suitable feeding mechanism. In Fig. 2 I have indicated rockable shafts 32 which carry forming arms 33 adapted to bend thel strand of wire 31' around the forming blocks 35. As the 80 wire 31 enters the slot 30 it is securely clamped in position so that movement in the slots during the forming operation performed by forming arms 33 is prevented. In the fabrication of a garment hanger it is customary to twist the ends of the wire to form a twisted neck and mechanism for accomplishing this consists partly of a member having a slot 56 formed therein. In orderI to elevate the finished article so as to disengage it from the slot 56 and to remove the n- 90 ished article from the slots 30,1 have provided the releasing and discharging mechanism, which forms the subject matter of the present invention. Swingably mounted intermediate its ends on each of the blocks 35`with a pin 37 is a releasing 95 bar 36 having on one end a notch 39, and provided on its opposite end with a roller 40 which is normallyVV heldin position to engage the cam y This presser bar 41 islstationary and mounted on lthe shaft 100 vor rod 34. The rod 34 is so located thatas the drum, 29 is` rotated, the roller 40 will engage the presser bar 41--immediately upon the finish of the formingl operation, so thatthe lower end .of the garment. hanger, which engages in the "slot 30 will befp'ressedoutwardlyintd the position shown in Fig.l 5.

Embracing 1the shaft is a sleeve or vbushing 42, which is held stationary by means ofthe clamp 43. 'Ifhi's 'clamp 43 permits of ya means forK 1 10 .1

securely fastening the bushing or sleeve 42 against rotation, and at the same time affords an easy means for adjusting the bushing or sleeve 42 circumferentially of the shaft 26. Carried on the end of the bushing or sleeve 42 is a cam disk 44.

Fixedly mounted on the shaft 26 and rotating therewith are the arms 45 and 46 which project radially outwardly therefrom. Projected through the arms 45 and 46, so as to be rockable is the shaft 47. A rod 48 is projected through the arms 45 and 46, this rod being also rockable. Fixedly mounted on the rod 48 is a collar 49 having teeth formed on one side as clearly appears in Fig. 4, adapted to mesh with the teeth formed on the end of the segment bar 50, which is ixedly mounted on the shaft 47. Fixedly mounted on the ends of the rod 48, and projecting outwardly therefrom, are the engagement fingers 51, each having a cut away portion to provide the shoulder 52. Fixedly mounted on the shaft 47 is one end of an arm 53, the other end of which carries a roller 54 riding on the periphery of the cam 44. 'I'he construction is such that as the drum .29 rotates and arrives at a predetermined pothe hanger 66 into. the position shown in Fig.4

5, the arms 45 and 46 will have moved into the vposition shown in full lines in Fig. 3; and segment bar 50 will have rocked to the position to bring, by a rocking of the rod 48, the fingers 41 into the position shown in full lines in Fig.

3 so that, the lower portion of the garment`^ hanger will be engaged by the shoulder 52. As the movement continues the garment hanger will be raised upwardly by the engagement fingers 51 so asto clear the slot 56.MAs the rotation of the shaft 26 continues through a rocking of ,theshaft 47 because of the engagement of the roller 54 with the cam 44, the rod 48 will be rocked so as to swing the engagement fingers 51 rearwardly so that a hooking of the garment hanger 66 by the engagement ngers will not be effected; and a passage of the garment hangery upwardly through the throw exerted thereon by the arms 45 ang 46 may be accomplished. The roller 54 is maintained pressed closely against the periphery of the cam 44 by the pressure exerted by the spring 55 which is connected to the lug 56 on the collar 57, which is fixedly mounted on the shaft 47.

As the arms 45 and 46 move upwardly, these arms travelling in the direction indicated by the arrow in Fig. 3. the engagement fingers 51 will carry the garment hanger upwardly and propel the same into the hood 59, provided with the wide compartment or receiving space 60. This hood is supported by suitable bracket 61 mounted on the frame or standards 12 and 13. Extending into the hood 59 is a supporting rail 62 -over which the neck or head of the garment hanger will engage, this rail 62 being downwardly inclined from the hood so that the garment hangers will slide downwardly and pass below the swingable cover 65, which is designed to check the speed of the garment hangers passing downwardly on the supporting rail 62. This supporting rail is supported by suitable'arm 63 carried by the bracket 64 which is attached to the frame or standards 12 and 13. With a mechanism such as described I have provided a simple and effective means of transferring the garment hangers from the forming mechanism to a suitable supporting rail or rack, and a simple effective means for releasing the garment hangers or completed articles from the forming mechanism.

While I have illustrated and described the preferred form of construction, I do not wish to ai. limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, whatv I claim as new and desire to secure by Letters Patent is:
